If a number is divisible by anything other than itself and 1, it's composite.

By using the divisibility rule for 3, we find that 117 is divisible by 3. That makes it composite.

It is a prime.

10, 25, 50 are the composite factors of the composite number 50. 2 and 5 are prime.

Yes you canYes. If a number is divisible by anything other than one or itself, it's composite.

Knowing the divisibility rules will help you by being able to recognize if a number has factors (other than one and itself) which are covered by the rules. This will save actually having to start doing divisions.

350 is a composite number. it can be divisible by 10, 35, 5, 2 etc. You will find it easier to tell between prime and composite if you know the divisibility rules. one simple one is that if a number ends with zero it is divisible by 10...there are a lot of other divisibility rules.

295 is composite - 5 x 59.

If the number can be multiplied by any number other than 1 it is a composite any other is prime

Yes

To determine which number is a prime or composite number, your number must only have two factors, the number itself and one, if it more then two factors then it is a composite number.

A number can be factored to determine whether it is prime or composite. A prime number has exactly 2 factors, 1 and the number itself. A composite number has more than two factors.

Prime numbers have two factors, composite numbers have more than two.

Prime numbers don't have factor trees. So if you can create a tree, your number's composite.

No. If the number has one factor (other than 1 and itself) it is a composite. However, to establish that a number is prime it needs to be checked for divisibility by each prime number up to the square root of the number. If the only factor found is 1, then it is a prime.

I can check them for divisibility by prime numbers.

If the number is divisible by any number and the quotient comes out to a whole number, then that number is composite. The number is prime when divided by a number, the answer is a decimal, then the number is prime. A prime number has exactly two factors, 1 and the number itself. Any number having more factors is a composite number.

No, you only need to determine if the number has any factors besides 1 and itself. If it does, it is a composite number.

16 is composite.

A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

It is a composite number.

It is not a prime number, it is a composite number.

It is not a prime number, it is a composite number.

It is a composite number, not a prime number.

No. There are techniques to find if it is prime
